About 10 days ago I saw a mink run across my goat yard in the daytime. I ran out with my dog to chase it away and it ran in the other direction and into my barn where I house my ducks and chickens in winter. I opened the doors and banged things making a lot of noise and yelling and it left pretty quickly. But it now knows the birds are there. I've been leaving a radio on and lights on in the barn at night. I leave the dog loose in the barn, changing up the times and length of time the dog is there. I've been patrolling with the dog. I set a have a heart trap 3 days ago but nothing has been caught. I'm wondering if anyone has used a baby monitor. My house is close enough to the barn that if I heard a commotion, I could reach them in time. Thanks in advance for any advice.
